Invisibility Cloak Could HideBuildings from Quakes
https://www.newscientist.com/article/dn17378-invisibility-cloak-could-hide-buildings-from-quakes/
“Borrowing from the physics of invisibility cloaks could make it possible to hide buildings from the devastating effects of earthquakes, say physicists in France and the UK.
The “earthquake cloak” idea comes from researchers in the UK, Italy and France, some of whom were the first to show that the physics of invisibility cloaks could have other applications – designing a cloak that could render objects “invisible” to destructive storm waves or tsunamis.”
In Search of an Earthquake-Proof Building
http://www.cnn.com/2010/TECH/03/02/earthquake.resistant.building/
“It's a sobering fact: Earthquakes alone don't kill people; collapsed buildings do.
But can people engineer buildings that wouldn't crumble when subjected to the rumblings of the Earth?”
Earthquake-Proof Skyscrapers Hide From SeismicWaves
http://www.popsci.com/science/article/2009-10/earthquake-proof-skyscraper
“Today's engineers buffer buildings with metal springs, ball bearings and rubber pads, all designed to sop up the energy from seismic waves. This summer, a team of physicists at the University of Liverpool in England and the FrenchNational Centre for Scientific Research tested a different strategy: redirect the waves altogether.”

Hey, guys. Thinking natural disasters.
When you think of natural disasters, there are several that come to mind. You have earthquakes, volcanoes, tornadoes, hurricanes. But, if I show you marshmallows, and I show you toothpicks, and tell you that we’re about to do an experiment that has to do with natural disasters, you’re gonna be, like, “Wait, what? Marshmallows and toothpicks, and natural disasters? But you.” Yeah, we’re going to do that, and I have a challenge for you. This is your challenge: I need you to get a bag of marshmallows, and you know what I love about this, is if your marshmallows ever get stale, the worst thing to do as a scientist is to throw them out. You can reuse anything, rather than making it into garbage.
Now, you have a challenge, and your challenge is this, can you create a multi-story structure, a structure, I think, that people can build? So, you have to make it multi-floored, which means more than one or two, I would say. And, here’s the kick, after you build it, it has to be standing. You’re not allowed to hold it up. It has to be free-standing and stable. Stable on the table. Gravity should not be knocking it down. Then, we’re going to simulate an earthquake. So, after you’re done, and you've made this really awesome structure, made out of only marshmallows and toothpicks, we’re going to shake the table, and we’re going to make an earthquake. And you can be, like, “Earthquake.” Just tremble and vibrate. And if your structure is still standing after 30 seconds of your simulated earthquake, you, my dear, are an engineer.
And check this out. Your structure’s actually gonna be three-dimensional, and all you need are marshmallows, and all we need are toothpicks. It doesn't matter if they’re the pointy type or the flat type, but, marshmallows are actually cylinder shapes. So, take a marshmallow, take a toothpick, put it through. You kinda have, it looks like you’re going to be working out with it, but you’re not. Now, think about how we can take this, and turn it into a really awesome three-dimensional shape. I’m going to start with this square, and then I’m going to build it up, and turn this square into a cube. Now I’m going to start going higher, just like this.
And the beauty about this experiment is, a bag of marshmallows is so inexpensive. Toothpicks, pretty much anybody has toothpicks at home. And, I can learn so many amazing concepts of engineering, building, gravity, center of gravity. You see, you really want this structure to have this amazing centered gravity, so that, If you really think about it, gravity’s always trying to knock you down. In fact, unfortunately, when we get a little older, you start to lean forward, because in your lifetime, your body has done nothing but battle gravity. Which is why our backs arch as we get older.
But, now look. I just made a three-dimensional cube. This is exactly one floor high. But the challenge is, could you create multi floors. And, as you get it to go higher and higher, it has to be stable. Stable on the table. You do not want it to be not balanced. The rules are you’re not allowed to hold it up. This is a challenge. And you’re only allowed to use toothpicks; you’re not allowed to get Scotch tape. Okay? That’s the challenge. And, as you can see already, mine is starting to lean. Gravity’s always pulling on it. I’m only gonna make mine three toothpicks high, just because I don’t need to make it bigger. That’s gonna be your challenge. Then, I’m gonna simulate an earthquake, and then, I’m gonna see if my structure is still standing.
And, there are other things that you can do, actually, to try to make your structure more stable. Questions like, ‛What happens if you added toothpicks across the squares?’ Something like this. Would this help? Would this help? Science is all about asking questions. Test them, and see what happens.
That’s two toothpicks high, and now I’m gonna go three toothpicks high. And by the way, if you don’t have marshmallows, you can actually use gumdrops. My whole point of this is, you can build and learn about structure and engineering and earthquakes, using any materials that you have at home. Uh-oh, gravity. Stop. There we go, it does get a little harder as you get higher. You gotta realize that, and you guys are gonna get frustrated. Starts to look like the leaning Tower of Marshmallows. And, I’m just going to put my toothpicks across the top, and then I’m gonna shake the table, and it’s earthquake time.
Will my structure still be standing? Will it fall? I

Seismic Conceptual Design of Building - Principles, Earthquake, seismic effect, tsunami, earthquake + building, disaster, seismology, earthquake resistent design.
In an earthquake, seismic waves arise from sudden movements in a rupture zone (active fault) in the earth's crust. Waves of different types and velocities travel different paths before reaching a building’s site and subjecting the local ground to various motions.
The ground moves rapidly back and forth in all directions, usually mainly horizontally, but also vertically.
What happens to the buildings? If the ground moves rapidly back and forth, then the foundations of the building are forced to follow these movements. The upper part of the building however would prefer to remain where it is because of its mass of inertia. This causes strong vibrations of the structure with resonance phenomena between the structure and the ground, and thus large internal forces. This frequently results in plastic deformation of the structure and substantial damage with local failures and, in extreme cases, collapse.
The ground motion parameters and other characteristic values at a location due to an earthquake of a given magnitude may vary strongly. They depend on numerous factors, such as the distance, direction, depth, and mechanism of the fault zone in the earth's crust (epicentre), as well as, in particular, the local soil characteristics (layer thickness, shear wave velocity). In comparison with rock, softer soils are particularly prone to substantial local amplification of the seismic waves. As for the response of a building to the ground motion, it depends on important structural characteristics (eigenfrequency, type of structure, ductility, etc).
Buildings must therefore be designed to cover considerable uncertainties and variations.
Once take care of principles (by HugoBachmann) as suggested in this video while designing building structures..!

Earthquake engineering

Earthquake engineering is an interdisciplinary branch of engineering that designs and analyzes structures, such as buildings and bridges, with earthquakes in mind. Its overall goal is to make such structures more resistant to earthquakes. An earthquake (or seismic) engineer aims to construct structures that will not be damaged in minor shaking and will avoid serious damage or collapse in a major earthquake. Earthquake engineering is the scientific field concerned with protecting society, the natural environment, and the man-made environment from earthquakes by limiting the seismic risk to socio-economically acceptable levels. Traditionally, it has been narrowly defined as the study of the behavior of structures and geo-structures subject to seismic loading; it is considered as a subset of structural engineering, geotechnical engineering, mechanical engineering, chemical engineering, applied physics, etc. However, the tremendous costs experienced in recent earthquakes have led to an expansion of its scope to encompass disciplines from the wider field of civil engineering, mechanical engineering and from the social sciences, especially sociology, political science, economics and finance.

Earthquake

An earthquake (also known as a quake, tremor or temblor) is the perceptible shaking of the surface of the Earth, resulting from the sudden release of energy in the Earth's crust that creates seismic waves. Earthquakes can be violent enough to toss people around and destroy whole cities. The seismicity or seismic activity of an area refers to the frequency, type and size of earthquakes experienced over a period of time.

Earthquakes are measured using observations from seismometers. The moment magnitude is the most common scale on which earthquakes larger than approximately 5 are reported for the entire globe. The more numerous earthquakes smaller than magnitude 5 reported by national seismological observatories are measured mostly on the local magnitude scale, also referred to as the Richter magnitude scale. These two scales are numerically similar over their range of validity. Magnitude 3 or lower earthquakes are mostly almost imperceptible or weak and magnitude 7 and over potentially cause serious damage over larger areas, depending on their depth. The largest earthquakes in historic times have been of magnitude slightly over 9, although there is no limit to the possible magnitude. Intensity of shaking is measured on the modified Mercalli scale. The shallower an earthquake, the more damage to structures it causes, all else being equal.

Engineer

An engineer is a practitioner of engineering, concerned with applying scientific knowledge, mathematics, and ingenuity to develop solutions for technical, societal and commercial problems. Engineers design materials, structures, and systems while considering the limitations imposed by practicality, regulation, safety, and cost. The word engineer is derived from the Latin words ingeniare ("to contrive, devise") and ingenium ("cleverness").

The work of engineers forms the link between scientific discoveries and their subsequent applications to human needs and quality of life.

Definition

In 1960, the Conference of Engineering Societies of Western Europe and the United States of America defined "professional engineer" as follows:

Roles and expertise

Design

Engineers develop new technological solutions. During the engineering design process, the responsibilities of the engineer may include defining problems, conducting and narrowing research, analyzing criteria, finding and analyzing solutions, and making decisions. Much of an engineer's time is spent on researching, locating, applying, and transferring information. Indeed, research suggests engineers spend 56% of their time engaged in various information behaviours, including 14% actively searching for information.

The Economist

The Economist is an English language weekly newspaper owned by the Economist Group and edited in offices based in London. Continuous publication began under founder James Wilson in September 1843. For historical reasons, The Economist refers to itself as a newspaper, but each print edition appears on small glossy paper like a news magazine. In 2006, its average weekly circulation was reported to be 1.5 million, about half of which were sold in the United States.

The publication belongs to The Economist Group. It is 50% owned by private investors and 50% by Exor, the Agnelli holding company, and the Rothschild banking family of England. Exor and the Rothschilds are represented on the Board of Directors. A board of trustees formally appoints the editor, who cannot be removed without its permission. Although The Economist has a global emphasis and scope, about two-thirds of the 75 staff journalists are based in the City of Westminster, London. As of March 2014, the Economist Group declared operating profit of £59m. Previous major shareholders include Pearson PLC.

Earthquake Protector: Shake Table Crash Testing

Comparative earthquake engineering experiments with 12-story building models: the right one is resting on a new type of seismic base isolation called "earthquake protectors", the left one is fixed to the base. The fundamental natural period of superstructures equals 1.2s, the isolated period of EarthquakeProtector equals 5.0s, the range of earthquake simulation periods is 0.02 - 2.00s. It is obvious: application of Earthquake Protector can raise a building's seismic sustainability dramatically.

Hey, guys. Thinking natural disasters.
When you think of natural disasters, there are several that come to mind. You have earthquakes, volcanoes, tornadoes, hurricanes. But, if I show you marshmallows, and I show you toothpicks, and tell you that we’re about to do an experiment that has to do with natural disasters, you’re gonna be, like, “Wait, what? Marshmallows and toothpicks, and natural disasters? But you.” Yeah, we’re going to do that, and I have a challenge for you. This is your challenge: I need you to get a bag of marshmallows, and you know what I love about this, is if your marshmallows ever get stale, the worst thing to do as a scientist is to throw them out. You can reuse anything, rather than making it into garbage.
Now, you have a challenge, and your challenge is this, can you create a multi-story structure, a structure, I think, that people can build? So, you have to make it multi-floored, which means more than one or two, I would say. And, here’s the kick, after you build it, it has to be standing. You’re not allowed to hold it up. It has to be free-standing and stable. Stable on the table. Gravity should not be knocking it down. Then, we’re going to simulate an earthquake. So, after you’re done, and you've made this really awesome structure, made out of only marshmallows and toothpicks, we’re going to shake the table, and we’re going to make an earthquake. And you can be, like, “Earthquake.” Just tremble and vibrate. And if your structure is still standing after 30 seconds of your simulated earthquake, you, my dear, are an engineer.
And check this out. Your structure’s actually gonna be three-dimensional, and all you need are marshmallows, and all we need are toothpicks. It doesn't matter if they’re the pointy type or the flat type, but, marshmallows are actually cylinder shapes. So, take a marshmallow, take a toothpick, put it through. You kinda have, it looks like you’re going to be working out with it, but you’re not. Now, think about how we can take this, and turn it into a really awesome three-dimensional shape. I’m going to start with this square, and then I’m going to build it up, and turn this square into a cube. Now I’m going to start going higher, just like this.
And the beauty about this experiment is, a bag of marshmallows is so inexpensive. Toothpicks, pretty much anybody has toothpicks at home. And, I can learn so many amazing concepts of engineering, building, gravity, center of gravity. You see, you really want this structure to have this amazing centered gravity, so that, If you really think about it, gravity’s always trying to knock you down. In fact, unfortunately, when we get a little older, you start to lean forward, because in your lifetime, your body has done nothing but battle gravity. Which is why our backs arch as we get older.
But, now look. I just made a three-dimensional cube. This is exactly one floor high. But the challenge is, could you create multi floors. And, as you get it to go higher and higher, it has to be stable. Stable on the table. You do not want it to be not balanced. The rules are you’re not allowed to hold it up. This is a challenge. And you’re only allowed to use toothpicks; you’re not allowed to get Scotch tape. Okay? That’s the challenge. And, as you can see already, mine is starting to lean. Gravity’s always pulling on it. I’m only gonna make mine three toothpicks high, just because I don’t need to make it bigger. That’s gonna be your challenge. Then, I’m gonna simulate an earthquake, and then, I’m gonna see if my structure is still standing.
And, there are other things that you can do, actually, to try to make your structure more stable. Questions like, ‛What happens if you added toothpicks across the squares?’ Something like this. Would this help? Would this help? Science is all about asking questions. Test them, and see what happens.
That’s two toothpicks high, and now I’m gonna go three toothpicks high. And by the way, if you don’t have marshmallows, you can actually use gumdrops. My whole point of this is, you can build and learn about structure and engineering and earthquakes, using any materials that you have at home. Uh-oh, gravity. Stop. There we go, it does get a little harder as you get higher. You gotta realize that, and you guys are gonna get frustrated. Starts to look like the leaning Tower of Marshmallows. And, I’m just going to put my toothpicks across the top, and then I’m gonna shake the table, and it’s earthquake time.
Will my structure still be standing? Will it fall? I

Seismic Conceptual Design of Building - Principles, Earthquake, seismic effect, tsunami, earthquake + building, disaster, seismology, earthquake resistent design.
In an earthquake, seismic waves arise from sudden movements in a rupture zone (active fault) in the earth's crust. Waves of different types and velocities travel different paths before reaching a building’s site and subjecting the local ground to various motions.
The ground moves rapidly back and forth in all directions, usually mainly horizontally, but also vertically.
What happens to the buildings? If the ground moves rapidly back and forth, then the foundations of the building are forced to follow these movements. The upper part of the building however would prefer to remain where it is because of its mass of inertia. This causes strong vibrations of the structure with resonance phenomena between the structure and the ground, and thus large internal forces. This frequently results in plastic deformation of the structure and substantial damage with local failures and, in extreme cases, collapse.
The ground motion parameters and other characteristic values at a location due to an earthquake of a given magnitude may vary strongly. They depend on numerous factors, such as the distance, direction, depth, and mechanism of the fault zone in the earth's crust (epicentre), as well as, in particular, the local soil characteristics (layer thickness, shear wave velocity). In comparison with rock, softer soils are particularly prone to substantial local amplification of the seismic waves. As for the response of a building to the ground motion, it depends on important structural characteristics (eigenfrequency, type of structure, ductility, etc).
Buildings must therefore be designed to cover considerable uncertainties and variations.
Once take care of principles (by HugoBachmann) as suggested in this video while designing building structures..!

Earthquake Protector: Shake Table Crash Testing

Comparative earthquake engineering experiments with 12-story building models: the right one is resting on a new type of seismic base isolation called "earthquake protectors", the left one is fixed to the base. The fundamental natural period of superstructures equals 1.2s, the isolated period of EarthquakeProtector equals 5.0s, the range of earthquake simulation periods is 0.02 - 2.00s. It is obvious: application of Earthquake Protector can raise a building's seismic sustainability dramatically.

Hey, guys. Thinking natural disasters.
When you think of natural disasters, there are several that come to mind. You have earthquakes, volcanoes, tornadoes, hurricanes. But, if I show you marshmallows, and I show you toothpicks, and tell you that we’re about to do an experiment that has to do with natural disasters, you’re gonna be, like, “Wait, what? Marshmallows and toothpicks, and natural disasters? But you.” Yeah, we’re going to do that, and I have a challenge for you. This is your challenge: I need you to get a bag of marshmallows, and you know what I love about this, is if your marshmallows ever get stale, the worst thing to do as a scientist is to throw them out. You can reuse anything, rather than making it into garbage.
Now, you have a challenge, and your challenge is this, can you create a multi-story structure, a structure, I think, that people can build? So, you have to make it multi-floored, which means more than one or two, I would say. And, here’s the kick, after you build it, it has to be standing. You’re not allowed to hold it up. It has to be free-standing and stable. Stable on the table. Gravity should not be knocking it down. Then, we’re going to simulate an earthquake. So, after you’re done, and you've made this really awesome structure, made out of only marshmallows and toothpicks, we’re going to shake the table, and we’re going to make an earthquake. And you can be, like, “Earthquake.” Just tremble and vibrate. And if your structure is still standing after 30 seconds of your simulated earthquake, you, my dear, are an engineer.
And check this out. Your structure’s actually gonna be three-dimensional, and all you need are marshmallows, and all we need are toothpicks. It doesn't matter if they’re the pointy type or the flat type, but, marshmallows are actually cylinder shapes. So, take a marshmallow, take a toothpick, put it through. You kinda have, it looks like you’re going to be working out with it, but you’re not. Now, think about how we can take this, and turn it into a really awesome three-dimensional shape. I’m going to start with this square, and then I’m going to build it up, and turn this square into a cube. Now I’m going to start going higher, just like this.
And the beauty about this experiment is, a bag of marshmallows is so inexpensive. Toothpicks, pretty much anybody has toothpicks at home. And, I can learn so many amazing concepts of engineering, building, gravity, center of gravity. You see, you really want this structure to have this amazing centered gravity, so that, If you really think about it, gravity’s always trying to knock you down. In fact, unfortunately, when we get a little older, you start to lean forward, because in your lifetime, your body has done nothing but battle gravity. Which is why our backs arch as we get older.
But, now look. I just made a three-dimensional cube. This is exactly one floor high. But the challenge is, could you create multi floors. And, as you get it to go higher and higher, it has to be stable. Stable on the table. You do not want it to be not balanced. The rules are you’re not allowed to hold it up. This is a challenge. And you’re only allowed to use toothpicks; you’re not allowed to get Scotch tape. Okay? That’s the challenge. And, as you can see already, mine is starting to lean. Gravity’s always pulling on it. I’m only gonna make mine three toothpicks high, just because I don’t need to make it bigger. That’s gonna be your challenge. Then, I’m gonna simulate an earthquake, and then, I’m gonna see if my structure is still standing.
And, there are other things that you can do, actually, to try to make your structure more stable. Questions like, ‛What happens if you added toothpicks across the squares?’ Something like this. Would this help? Would this help? Science is all about asking questions. Test them, and see what happens.
That’s two toothpicks high, and now I’m gonna go three toothpicks high. And by the way, if you don’t have marshmallows, you can actually use gumdrops. My whole point of this is, you can build and learn about structure and engineering and earthquakes, using any materials that you have at home. Uh-oh, gravity. Stop. There we go, it does get a little harder as you get higher. You gotta realize that, and you guys are gonna get frustrated. Starts to look like the leaning Tower of Marshmallows. And, I’m just going to put my toothpicks across the top, and then I’m gonna shake the table, and it’s earthquake time.
Will my structure still be standing? Will it fall? I

Seismic Conceptual Design of Building - Principles, Earthquake, seismic effect, tsunami, earthquake + building, disaster, seismology, earthquake resistent design.
In an earthquake, seismic waves arise from sudden movements in a rupture zone (active fault) in the earth's crust. Waves of different types and velocities travel different paths before reaching a building’s site and subjecting the local ground to various motions.
The ground moves rapidly back and forth in all directions, usually mainly horizontally, but also vertically.
What happens to the buildings? If the ground moves rapidly back and forth, then the foundations of the building are forced to follow these movements. The upper part of the building however would prefer to remain where it is because of its mass of inertia. This causes strong vibrations of the structure with resonance phenomena between the structure and the ground, and thus large internal forces. This frequently results in plastic deformation of the structure and substantial damage with local failures and, in extreme cases, collapse.
The ground motion parameters and other characteristic values at a location due to an earthquake of a given magnitude may vary strongly. They depend on numerous factors, such as the distance, direction, depth, and mechanism of the fault zone in the earth's crust (epicentre), as well as, in particular, the local soil characteristics (layer thickness, shear wave velocity). In comparison with rock, softer soils are particularly prone to substantial local amplification of the seismic waves. As for the response of a building to the ground motion, it depends on important structural characteristics (eigenfrequency, type of structure, ductility, etc).
Buildings must therefore be designed to cover considerable uncertainties and variations.
Once take care of principles (by HugoBachmann) as suggested in this video while designing building structures..!

In an earthquake, seismic waves arise from sudden movements in a rupture zone (active fault) in the earth's crust. Waves of different types and velocities travel different paths before reaching a building’s site and subjecting the local ground to various motions.
The ground moves rapidly back and forth in all directions, usually mainly horizontally, but also vertically.
What happens to the buildings? If the ground moves rapidly back and forth, then the foundations of the building are forced to follow these movements. The upper part of the building however would prefer to remain where it is because of its mass of inertia. This causes strong vibrations of the structure with resonance phenomena between the structure and the ground, and thus large internal forces. This frequently results in plastic deformation of the structure and substantial damage with local failures and, in extreme cases, collapse.
The ground motion parameters and other characteristic values at a location due to an earthquake of a given magnitude may vary strongly. They depend on numerous factors, such as the distance, direction, depth, and mechanism of the fault zone in the earth's crust (epicentre), as well as, in particular, the local soil characteristics (layer thickness, shear wave velocity). In comparison with rock, softer soils are particularly prone to substantial local amplification of the seismic waves. As for the response of a building to the ground motion, it depends on important structural characteristics (eigenfrequency, type of structure, ductility, etc).
Buildings must therefore be designed to cover considerable uncertainties and variations.
Once take care of principles (by HugoBachmann) as suggested in this video while designing building structures..!

Earthquake Protector: Shake Table Crash Testing

Comparative earthquake engineering experiments with 12-story building models: the right one is resting on a new type of seismic base isolation called "earthquake protectors", the left one is fixed to the base. The fundamental natural period of superstructures equals 1.2s, the isolated period of EarthquakeProtector equals 5.0s, the range of earthquake simulation periods is 0.02 - 2.00s. It is obvious: application of Earthquake Protector can raise a building's seismic sustainability dramatically.

Invisibility Cloak Could HideBuildings from Quakes
https://www.newscientist.com/article/dn17378-invisibility-cloak-could-hide-buildings-from-quakes/
“Borrowing from the physics of invisibility cloaks could make it possible to hide buildings from the devastating effects of earthquakes, say physicists in France and the UK.
The “earthquake cloak” idea comes from researchers in the UK, Italy and France, some of whom were the first to show that the physics of invisibility cloaks could have other applications – designing a cloak that could render objects “invisible” to destructive storm waves or tsunamis.”
In Search of an Earthquake-Proof Building
http://www.cnn.com/2010/TECH/03/02/earthquake.resistant.building/
“It's a sobering fact: Earthquakes alone don't kill people; collapsed buildings do.
But can people engineer buildings that wouldn't crumble when subjected to the rumblings of the Earth?”
Earthquake-Proof Skyscrapers Hide From SeismicWaves
http://www.popsci.com/science/article/2009-10/earthquake-proof-skyscraper
“Today's engineers buffer buildings with metal springs, ball bearings and rubber pads, all designed to sop up the energy from seismic waves. This summer, a team of physicists at the University of Liverpool in England and the FrenchNational Centre for Scientific Research tested a different strategy: redirect the waves altogether.”

Hey, guys. Thinking natural disasters.
When you think of natural disasters, there are several that come to mind. You have earthquakes, volcanoes, tornadoes, hurricanes. But, if I show you marshmallows, and I show you toothpicks, and tell you that we’re about to do an experiment that has to do with natural disasters, you’re gonna be, like, “Wait, what? Marshmallows and toothpicks, and natural disasters? But you.” Yeah, we’re going to do that, and I have a challenge for you. This is your challenge: I need you to get a bag of marshmallows, and you know what I love about this, is if your marshmallows ever get stale, the worst thing to do as a scientist is to throw them out. You can reuse anything, rather than making it into garbage.
Now, you have a challenge, and your challenge is this, can you create a multi-story structure, a structure, I think, that people can build? So, you have to make it multi-floored, which means more than one or two, I would say. And, here’s the kick, after you build it, it has to be standing. You’re not allowed to hold it up. It has to be free-standing and stable. Stable on the table. Gravity should not be knocking it down. Then, we’re going to simulate an earthquake. So, after you’re done, and you've made this really awesome structure, made out of only marshmallows and toothpicks, we’re going to shake the table, and we’re going to make an earthquake. And you can be, like, “Earthquake.” Just tremble and vibrate. And if your structure is still standing after 30 seconds of your simulated earthquake, you, my dear, are an engineer.
And check this out. Your structure’s actually gonna be three-dimensional, and all you need are marshmallows, and all we need are toothpicks. It doesn't matter if they’re the pointy type or the flat type, but, marshmallows are actually cylinder shapes. So, take a marshmallow, take a toothpick, put it through. You kinda have, it looks like you’re going to be working out with it, but you’re not. Now, think about how we can take this, and turn it into a really awesome three-dimensional shape. I’m going to start with this square, and then I’m going to build it up, and turn this square into a cube. Now I’m going to start going higher, just like this.
And the beauty about this experiment is, a bag of marshmallows is so inexpensive. Toothpicks, pretty much anybody has toothpicks at home. And, I can learn so many amazing concepts of engineering, building, gravity, center of gravity. You see, you really want this structure to have this amazing centered gravity, so that, If you really think about it, gravity’s always trying to knock you down. In fact, unfortunately, when we get a little older, you start to lean forward, because in your lifetime, your body has done nothing but battle gravity. Which is why our backs arch as we get older.
But, now look. I just made a three-dimensional cube. This is exactly one floor high. But the challenge is, could you create multi floors. And, as you get it to go higher and higher, it has to be stable. Stable on the table. You do not want it to be not balanced. The rules are you’re not allowed to hold it up. This is a challenge. And you’re only allowed to use toothpicks; you’re not allowed to get Scotch tape. Okay? That’s the challenge. And, as you can see already, mine is starting to lean. Gravity’s always pulling on it. I’m only gonna make mine three toothpicks high, just because I don’t need to make it bigger. That’s gonna be your challenge. Then, I’m gonna simulate an earthquake, and then, I’m gonna see if my structure is still standing.
And, there are other things that you can do, actually, to try to make your structure more stable. Questions like, ‛What happens if you added toothpicks across the squares?’ Something like this. Would this help? Would this help? Science is all about asking questions. Test them, and see what happens.
That’s two toothpicks high, and now I’m gonna go three toothpicks high. And by the way, if you don’t have marshmallows, you can actually use gumdrops. My whole point of this is, you can build and learn about structure and engineering and earthquakes, using any materials that you have at home. Uh-oh, gravity. Stop. There we go, it does get a little harder as you get higher. You gotta realize that, and you guys are gonna get frustrated. Starts to look like the leaning Tower of Marshmallows. And, I’m just going to put my toothpicks across the top, and then I’m gonna shake the table, and it’s earthquake time.
Will my structure still be standing? Will it fall? I

Hey, guys. Thinking natural disasters.
When you think of natural disasters, there are several that come to mind. You have earthquakes, volcanoes, tornadoes, hurricanes. But, if I show you marshmallows, and I show you toothpicks, and tell you that we’re about to do an experiment that has to do with natural disasters, you’re gonna be, like, “Wait, what? Marshmallows and toothpicks, and natural disasters? But you.” Yeah, we’re going to do that, and I have a challenge for you. This is your challenge: I need you to get a bag of marshmallows, and you know what I love about this, is if your marshmallows ever get stale, the worst thing to do as a scientist is to throw them out. You can reuse anything, rather than making it into garbage.
Now, you have a challenge, and your challenge is this, can you create a multi-story structure, a structure, I think, that people can build? So, you have to make it multi-floored, which means more than one or two, I would say. And, here’s the kick, after you build it, it has to be standing. You’re not allowed to hold it up. It has to be free-standing and stable. Stable on the table. Gravity should not be knocking it down. Then, we’re going to simulate an earthquake. So, after you’re done, and you've made this really awesome structure, made out of only marshmallows and toothpicks, we’re going to shake the table, and we’re going to make an earthquake. And you can be, like, “Earthquake.” Just tremble and vibrate. And if your structure is still standing after 30 seconds of your simulated earthquake, you, my dear, are an engineer.
And check this out. Your structure’s actually gonna be three-dimensional, and all you need are marshmallows, and all we need are toothpicks. It doesn't matter if they’re the pointy type or the flat type, but, marshmallows are actually cylinder shapes. So, take a marshmallow, take a toothpick, put it through. You kinda have, it looks like you’re going to be working out with it, but you’re not. Now, think about how we can take this, and turn it into a really awesome three-dimensional shape. I’m going to start with this square, and then I’m going to build it up, and turn this square into a cube. Now I’m going to start going higher, just like this.
And the beauty about this experiment is, a bag of marshmallows is so inexpensive. Toothpicks, pretty much anybody has toothpicks at home. And, I can learn so many amazing concepts of engineering, building, gravity, center of gravity. You see, you really want this structure to have this amazing centered gravity, so that, If you really think about it, gravity’s always trying to knock you down. In fact, unfortunately, when we get a little older, you start to lean forward, because in your lifetime, your body has done nothing but battle gravity. Which is why our backs arch as we get older.
But, now look. I just made a three-dimensional cube. This is exactly one floor high. But the challenge is, could you create multi floors. And, as you get it to go higher and higher, it has to be stable. Stable on the table. You do not want it to be not balanced. The rules are you’re not allowed to hold it up. This is a challenge. And you’re only allowed to use toothpicks; you’re not allowed to get Scotch tape. Okay? That’s the challenge. And, as you can see already, mine is starting to lean. Gravity’s always pulling on it. I’m only gonna make mine three toothpicks high, just because I don’t need to make it bigger. That’s gonna be your challenge. Then, I’m gonna simulate an earthquake, and then, I’m gonna see if my structure is still standing.
And, there are other things that you can do, actually, to try to make your structure more stable. Questions like, ‛What happens if you added toothpicks across the squares?’ Something like this. Would this help? Would this help? Science is all about asking questions. Test them, and see what happens.
That’s two toothpicks high, and now I’m gonna go three toothpicks high. And by the way, if you don’t have marshmallows, you can actually use gumdrops. My whole point of this is, you can build and learn about structure and engineering and earthquakes, using any materials that you have at home. Uh-oh, gravity. Stop. There we go, it does get a little harder as you get higher. You gotta realize that, and you guys are gonna get frustrated. Starts to look like the leaning Tower of Marshmallows. And, I’m just going to put my toothpicks across the top, and then I’m gonna shake the table, and it’s earthquake time.
Will my structure still be standing? Will it fall? I

Seismic Conceptual Design of Building - Principles, Earthquake, seismic effect, tsunami, earthquake + building, disaster, seismology, earthquake resistent design.
In an earthquake, seismic waves arise from sudden movements in a rupture zone (active fault) in the earth's crust. Waves of different types and velocities travel different paths before reaching a building’s site and subjecting the local ground to various motions.
The ground moves rapidly back and forth in all directions, usually mainly horizontally, but also vertically.
What happens to the buildings? If the ground moves rapidly back and forth, then the foundations of the building are forced to follow these movements. The upper part of the building however would prefer to remain where it is because of its mass of inertia. This causes strong vibrations of the structure with resonance phenomena between the structure and the ground, and thus large internal forces. This frequently results in plastic deformation of the structure and substantial damage with local failures and, in extreme cases, collapse.
The ground motion parameters and other characteristic values at a location due to an earthquake of a given magnitude may vary strongly. They depend on numerous factors, such as the distance, direction, depth, and mechanism of the fault zone in the earth's crust (epicentre), as well as, in particular, the local soil characteristics (layer thickness, shear wave velocity). In comparison with rock, softer soils are particularly prone to substantial local amplification of the seismic waves. As for the response of a building to the ground motion, it depends on important structural characteristics (eigenfrequency, type of structure, ductility, etc).
Buildings must therefore be designed to cover considerable uncertainties and variations.
Once take care of principles (by HugoBachmann) as suggested in this video while designing building structures..!
